Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional tilt-wing and tiltrotor aircraft designs are used, then horizontal flying efficiency is improved, but agility and aerobatic capabilities deteriorate
Solution Approach 1:
The aircraft is divided into independent wing assemblies, each with its own motor and control system. This segmentation allows each wing to be controlled independently, enabling complex aerobatic maneuvers while maintaining efficient horizontal flight when both wings operate in unison.
Solution Approach 2:
The wing assemblies are designed to be dynamically tiltable with individually adjustable angles. This dynamic capability allows the aircraft to transition between efficient horizontal flight configuration and high-agility aerobatic configurations by adjusting wing tilt angles in real-time.
2Adaptability or versatility
If individual tilting of each wing assembly is implemented, then agility is improved, but device complexity increases
Solution Approach 1:
By segmenting the control system into independent modules for each wing assembly, the patent manages complexity through modularity. Each segment handles its own tilting and propulsion, simplifying the overall control architecture while enabling agile maneuvers.
Solution Approach 2:
Each wing assembly serves multiple functions: propulsion, lift generation, and attitude control. This multi-functionality reduces the need for separate dedicated components for each function, thereby managing device complexity while achieving enhanced agility.
3Adaptability or versatility
If differential tilting angles are used for each wing, then aerobatic ability is improved, but control system complexity increases
Solution Approach 1:
The control system dynamically adjusts wing tilt angles based on real-time flight conditions and desired maneuvers. This dynamic control enables complex aerobatic abilities while managing system complexity through adaptive algorithms that optimize control signals.
Solution Approach 2:
The control system incorporates feedback mechanisms to monitor wing positions and flight attitude, automatically adjusting differential tilting angles to achieve desired aerobatic maneuvers. This feedback control manages complexity by automating the coordination of multiple control surfaces.

Function Achieved in This Case
This approach achieves improved agility and aerobatic ability while maintaining comparable aerodynamic efficiency to fixed-wing aircraft and vertical take-off capability.
Implementation Method 1
one propeller that is driven by the power plant for providing propulsion
Implementation Method 2
The fuselage typically also carries a tail or empennage for stability and control... When the aircraft travels forwards, air flows over the wings which are shaped to create lift

AI summary
Example embodiment provides an aircraft with improved agility. The aircraft includes a main body, at least two wing assemblies, at least two motors, and a controller. The wing assemblies are attached to the main body. Each motor tilts one wing assembly with a tilting angle. The controller is connected with the motors for controlling the tilting angle of the wing assembly. Each wing assembly further includes a wing, a power plant, and a propeller that is driven by the power plant for providing propulsion. Each wing assembly tilts with an individual tilting angle, so that the aircraft can fly with improved agility. The power plants and propellers on the wings can each be controlled independently in synchronism with the tilting wings.
